Yes, the MediaMonkey Library will contain any changes you made in MediaMonkey to the MKV files. MediaMonkey just can't write the changes to the MKV files themselves.

Thanks for the replies. I can't really replicate as it appears to happen at random.

While MM5 doesn't add tags to the file itself, it still creates tags in the Database, correct?

I'm running the testing version, so if it happens in the meantime, then I'll submit.

For MM5 MKV is read-only format, we do not have editing tags implemented, I do not see any way how MM5 could strip tags out from the file itself, as it cannot edit it at all.

Hi,
Please try and use 5.0.4.2653+ for testing. I am trying whole day and can't replicate

I've noticed that I'll have an mkv video on playback and at some point (I'm unable to figure out when), the tags will get stripped out. Not all of them, but oftentimes it's the following tags: Title, Artist, Album, Genre. The Date remains the same, and the Filename doesn't get removed, but these tags do (as in they're totally blank).

I have a hard time replicating this. I think it might happen after I've watched, paused, watched, paused for a number of times (which I usually do). But it doesn't happen with a full stop that I can tell, nor after a restart of MM.

This has happened with a variety of video files, but they're all .mkv format.

EDIT: I'm using 5.0.3.2627
